A percentile counts historical readings below the current value, plus half of readings tied with it, as a share of the reference window. The reference window is five years of weekly observations for that same stock and metric. A reading near the bottom of that range describes history; it is not a recommendation.
We round the displayed percentile to a whole number. Values from 0 to 10 are Historically low; 11 to 30 are Below its usual range; 31 to 69 are Within its usual range; 70 to 89 are Above its usual range; 90 to 100 are Historically high.
Financial inputs come from SEC EDGAR company facts. Trailing twelve months means the most recent four quarters available at a weekly observation date. We align fiscal periods, account for stock splits and use filing dates to keep later reports out of earlier observations.
P/E divides price by trailing earnings per share. P/S divides market value by trailing revenue. Enterprise value, or EV, adds debt and subtracts cash from market value; EV/Sales and EV/EBITDA compare it with trailing revenue or earnings before interest, taxes, depreciation and amortization. Forward P/E, when shown, is separate context and never enters a historical percentile.
The shaded band spans the middle half of five-year readings. Its center reference is the median, the midpoint reading. The chart range controls how much history is visible; choosing 10Y or All does not change the five-year percentile window.
Negative earnings do not produce a meaningful P/E. Very small denominators, insufficient history and inconsistent filings can also prevent ranking. Data under review is withheld from public comparisons. We do not present sample data as current valuation evidence.
Coverage favors US companies with usable SEC filings. Spin-offs, acquisitions, restatements and changes in reporting can break historical comparability. Read the dated source note on each page and inspect the company’s filings before drawing conclusions.
The refresh pipeline checks for new filings and market prices daily. Historical observations remain weekly. Each data view carries its latest available date, which can lag the current day. Article analysis keeps its original as-of date; the live module below it shows current readings separately.
